Abstract

As an organ that absorbs food, the intestine can be damaged when interacting directly with lead (Pb). Gamma Co-60 irradiated chitosan, and vitamin E combination potentially can help reduce free radical damage to intestinal organs. This study examines the efficacy of gamma Co-60 irradiated chitosan and vitamin E combination in protecting the intestinal tissue of rats exposed to Pb acetate. The 24 rats were grouped into 6 groups, each 4 rats; were induced with Pb acetate, except the control group. The negative control group was only induced Pb acetate. The positive control group had additional treatment of irradiated chitosan. The treatment group (1-3) was treated using the combination of gamma Co-60 irradiated chitosan at a dose of 64 mg/kg BW and vitamin E 1000 IU at a dose of 1.44; 2.16, 3.00 mg/kg BW, respectively, for forty days. The research parameters observed are edema, degeneration, necrosis, erosion of the intestinal villi, and lysis of the intestinal villi. Intestinal histology appearance data in all groups were analyzed descriptively. The result shows that a combination of Gamma Co-60 irradiated chitosan at a dose of 64 mg/kg BW and vitamin E at a dose of 1.44 mg/kg BW effectively reduced lead cytotoxicity in the intestinal tissue of Pb acetate-induced rats. The larger the dose of vitamin E has the potential to produce pro-oxidants, which will increase the toxic effect on intestinal tissue. Gamma Co-60 irradiated chitosan, and vitamin E combination at the right dose has the potential to be developed as a supplement to reduce the toxic effects of chronic lead exposure. Especially for people who, for some reason, cannot avoid chronic lead exposure.

Abstract

One of the management of diabetics is to maintain stable glucose levels. Often diabetes treatment combines chemical drugs with medicinal plants. People have consumed a lot of Moringa leaves which are believed to be able to maintain body condition. One of the benefits of Moringa leaves with phytochemical components in it is as a hepatoprotector. The aim of this study was to analyze the role of Moringa leaf extract on liver function parameters of hyperglycemic rats. There were 4 groups, normal control (K0), hyperglycemic rats with induction of alloxan 125 mg/kg bw and divided into three groups treated with moringa leaf extract at a dose of 0 mg (K1), 200 mg (T1) and 400 mg/kg bw (T2 ) for 21 days. The variables measured were aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels, total cholesterol. Data were analyzed with Anova P0.05 and Least Significance Different (LSD) follow-up test. The results showed that the levels of AST and ALT were highest in the K1 group which then decreased significantly in the group that received Moringa extract (T1 and T2). Statistically there was a significant difference (p0.05) between the control and treatment groups. Cholesterol levels in the control group were significantly lower than the diabetes and treatment groups, but there was no significant difference between the treatment groups. The conclusion is that Moringa leaf extract has an effect on reducing liver enzyme levels and cholesterol in hyperglycemic rats. This research adds to the study of the hepatoprotective potential of Moringa leaf extract in hyperglycemic rats.
